Which of the Following Statements About Evolution of Behaviour Is

Question

Which of the following statements about evolution of behaviour is correct?
A)Natural selection will favour behaviour that enhances survival and reproduction.
B)An animal may show behaviour that minimizes reproductive fitness.
C)If a behaviour is less than optimal, it will eventually become optimal through natural selection.
D)Innate behaviours can never be altered by natural selection.
E)All of the statements are correct.

Accepted Answer

Natural selection will favour behaviour that enhances an individual's chances of survival and reproduction, as these are the key drivers of evolution. Behaviours that do not contribute to these goals are less likely to be favoured by natural selection and may even be selected against. While not all behaviour may be optimal, natural selection will continuously work to improve behaviour over time. Innate behaviours can be altered by natural selection, as mutations in genes underlying these behaviours can result in new or altered behaviours that are better suited to an organism's environment.
